Bank of Italy Partial Credit Guarantee Schemes – Experiences and Lessons A joint conference by the World Bank, Rensselaer Polytechnic Institute, and the Journal of Financial Stability The World Bank, Washington DC March 13-14, 2008 Firms as Monitors of Other Firms: Mutual Loan Guarantee Consortia and SME Finance Francesco Columba, Leonardo Gambacorta, Paolo Emilio Mistrulli The usual disclaimer applies. The opinions are those of the authors only and in no way involve the responsibility of the Bank of Italy. Bank of Italy Motivation • In Europe two thirds of all jobs are provided by SMEs, this notwithstanding the literature shows that because of their opaqueness SMEs may encounter difficulties in accessing the credit market. • Information asymmetries may be partially mitigated with collateral or relationship lending, but SMEs due to lack of collateral or of a long credit history may still find difficult to raise external finance. • We analyse an alternative lending technology for SMEs, Mutual Loan Guarantee Consortia (MLGC), similar to group lending. • With MLGC a group of SMEs with individual limited collateral are linked by a joint responsibility. Each SME contibutes to a guarantee fund that is used as collateral to loans granted to MLGC members. • Italy is a telling case given the importance of MLGCs and SMEs . • We aim to ascertain if MLGCs help to mitigate information asymmetries for SMEs. The World Bank, Washington DC Columba, Gambacorta and Mistrulli - Firms as Monitors of Other Firms 2 Bank of Italy Outline • MLGCs characteristics. • Stylized facts on MLGCs. • Effects of MLGCs on the cost of credit. • Deeper into MLGCs: peer monitoring and external funds. • Effects of MLGCs on the quality of credit. • Conclusions. The World Bank, Washington DC Columba, Gambacorta and Mistrulli - Firms as Monitors of Other Firms 3 Bank of Italy Italian Mutual Loan Guarantee Consortia characteristics • MLGCs are registered at the Bank of Italy and are subject to prudential regulation only after a treshold of activity. • The capital has to be more than 0.25 mln euro and at least 20% has to be subscribed by affiliated firms; third parties (public and alike) may subscribe capital. • MLGCs ease SMEs access to credit in three ways: – post collateral drawed from guarantee funds deposited in a bank by affiliated firms and external bodies (usually monetary funds with a loan-to-guarantee ratio between 10 and 20); – selecting and monitoring firms; – negotiating collectively with banks financing conditions. • MLGCs are grouped in 5 main federations along business sectors. The World Bank, Washington DC Columba, Gambacorta and Mistrulli - Firms as Monitors of Other Firms 4 Bank of Italy Stylized facts for Italian MLGCs • The MLGCs are around 1,000: their activity is stronger in Northern Italy, whereas half of the MLGCs are in the South. • The average number of firms affiliated to a MLGC is 1,900. • The guarantees provided by MLGCs are 8 billions euro for loans of 20 billions euro. • 80% of guarantees are monetary, the rest are personal. • 55% of Italian banks lent to SMEs affiliated to a MLGCs; 22% of large and medium banks, 46% of small banks. • Typically a MLGC has a convention with 10 banks. The World Bank, Washington DC Columba, Gambacorta and Mistrulli - Firms as Monitors of Other Firms 5 Bank of Italy Effects of MLGCs on the cost of credit • Unique data-set from Italian Credit Register and Survey on Interest Rates with 263,000 SMEs that had a loan in 2005; 46,000 SMEs had a guarantee posted by a MLGC. • Test of the effects of the posting of a MLGC guarantee on the interest rate paid on a bank loan to a SME. • Benchmark model. • Robustness. • Beyond robustness.
